CF2197B.Array and Permutation
Array and Permutation
Given a permutation of length and an array of length .
We call the permutation generating for the array if the array can be obtained from the permutation by applying some number of operations (possibly zero) of the following type:
Choose an index () and perform one of two replacements:
- ;
- .
In other words, in one operation, you can choose two adjacent elements of the array and copy the value of one into the other.
You are required to report whether the permutation is generating for the array .
A permutation of length is an array consisting of distinct integers from to in arbitrary order. For example, is a permutation, but is not a permutation ( appears twice in the array), and is also not a permutation ( but there is in the array).
Input
Each test contains multiple test cases. The first line contains the number of test cases (). The description of the test cases follows.
The first line of each test case contains a single integer () — the length of the array and the permutation.
The second line of each test case contains integers () — the elements of the permutation.
The third line of each test case contains integers () — the elements of the array.
It is guaranteed that the sum of across all test cases does not exceed .
Output
For each test case, output "YES" if the permutation is generating for the array , otherwise output "NO".
You may output each letter in any case (lowercase or uppercase). For example, the strings "yEs", "yes", "Yes", and "YES" will be accepted as a positive answer.
Note
In the first test case, the array is generated from the permutation using one operation:
- and .
In the second test case, it is impossible to obtain from .
In the third test case, it is necessary to perform operations:
- and ;
- and .
